Hi.
I'm trying to mine altcoins using lyra2v2, groestl, myr-gr algos using ccminer (tpruvot) under Ubuntu 16.04. I have rigs running on Intel Celeron G1840 and rigs running on AMD Athlon X245 CPUs. GPU config is the same: 4x 1060 Palit StormX 3gb, 1x 1050ti MSI/Palit, using PCIE splitter. Oddly enough, I found out that in groestl I get ~ 96 khs on Intel rigs, and around 85 khs on AMD rigs. On lyra2v2 difference is even bigger. Overclock settings are the same, +700 memory, +240 core. Driver ver 384.66 on all rigs. It's not a particular GPU, all videocards run slightly slower on AMD rigs.
Mining ETHash coins using Claymore on all rigs produces roughly same hashrate (~ 108 mhs), same goes for mining Equihash using EWBF or ZM miner (~ 1350 sols). Is it that ccminer not optimized well for AMD CPUs and motherboards? Any idea why this may be happening? I tried to recompile ccminer on an AMD rig, it produced file of slightly different size, but no improvement in hashrate.
